"... In PAGE 6: ... In a nutshell, either the available functionality provides only hypertext features, or the hypertext support functionality is limited to some model areas. In Table1 we compare our approach with related implementations. Dynamic Design (Bigelow 1988) is a configuration management environment, which uses hypertext links for specifying configurations, attaching annotations and associating design objects and source code.... ..."

"... In PAGE 14: ... It is a matter of personal taste in mathematics and computing, but I generally use one or two character identifiers in an algebraic exposition while employing GAMS parameters with as many as 10 characters. In order to avoid potential confusion due to differences in notation, Table8 gives a cross-reference of symbols used in the algebraic formulation in this paper to the GAMS parameters which define the benchmark value of these variables in the GTAPinGAMS dataset.... In PAGE 20: ... The first set of variables are unit demand and supply functions, corresponding to the symbols from the algebraic formulation above. (See Table8 .) Demand and supply functions are represented implicitly in the MPSGE model, but for simplicity these are introduced as separate symbols in the algebraic model.... ..."

"... In PAGE 9: ... Examinig table 2 we may draw the conclusion that only the performance of a depth- first search strategy, or another strategy very close to it, by our simulated user yields a proper perception of the structure of the HHO-graph. Table3 shows a global summary of the results of all experiments for class-2 users. Small versus large numbers of steps are compared, with and without the highlighting facility, and for documents of different size and with a different percentage of cross- reference links.... ..."

"... In PAGE 7: ...ebsites used HTTP. Four percent used FTP and 2% used GOPHER. Other protocols such as NEWS were rarely used. Spearman correlation analysis showed that the number of hypermedia links (HTTP) provided by a website is positively correlated with the research and teaching assessment scores of the hosting department (see Table2 ). On the other hand, the number of Table 2 Correlation between hypertext references and organisational profile (p , 0.... ..."

"... In PAGE 25: ....5.7 Summary of Composite Data Models A summary of the containment characteristics and version selection capabilities of composite-based hypertext versioning systems is presented in Table 1 below. In Table2 , linking, versioning of composites, merging, and variant support is summarized. System Composites are called Containable items Containment type Version selection PIE [32] layer, context A layer contains a set of changes to nodes and links, a context is the sum of several layers.... ..."

"... In PAGE 8: ...A list of operations supported in OM is given in Table1 . The algebra includes operations suchasunion, intersection, di#0Berence, cross product, #0Datten, selection, map and reduce as well as special operations over binary collections suchas domain, range, inverse, compose and closure.... In PAGE 9: ... The OM model also supports special operations over binary collections. Some of them are listed in the second part of Table1 . The domain operation takes a binary collection and forms a collection of all the objects that appear as the #0Crst element of a pair of objects #3Coid 1 , oid 2 #3E belonging to the binary col- lection, whereas the range operation returns a collection containing the second elements of such pairs.... ..."
